I need some tips please guys.

I'm converting my PNV r30 coupe to manual as i've finally found everything I need.

How do i get the bits out of the manual r30? Do i have to get the dash out to get the pedal box out? Any suggestions on driveshaft and clutch etc?

just general not R30 specific

tailshaft is easy, 4 bolts on the diff, use 2 spanners. if its got a centre bearing unbolt that and slide it out of theback of the gearbox

drain the clutch lines via the bleed valve (or unbolt the line) on the clutch slave, unbolt it from the bellhousing

undo any earth wires, reverse swicth wires, ect going into the box. make sure you get all of them

unbolt the shifter linkage, youll probably have to take out the centre concole and the shifter boot. might also get away with not having to unbolt it.

start undoing the bellhousing bolts, using lots of extentions.

undo the gearbox Xmember bolts. this is where it gets dangerous as the box is only supported by the input shaft

everything unbolted and out of the way, slide the box back and once the shaft is free, drop it out. if its a smaller box you should be able to lift it yourself, but it sucks doing it on the ground!

umm clutch stuff unbolt the master from the firewall (careful of spilling fluid) and unbolt the linkage. then shove yourself doen under the dash and get the pedal out and stuff out

They're pretty damn heavy. We used two jacks and three people to be safe. It was easy enough, just keep the box stable as you lower it down. You might want to unbolt one of the front wheels so that you can get the box out easily once removed.

Sure you've got everything you need?

I got it out.

I got:

Gearbox

Pedal box

Clutch Cylinders

Front and rear driveshafts

This driveshaft cage

Gearbox crossmember

i jsut have to get a clutch and flywheel (sorting that out now).

DO you guys reckon it'll be possible to install the manual box with the car on axle stands?? I'll be doing it as soon as i get my clutch and flywheel.

Also, the plug that goes to the loom on the manual. I noticed my auto has the same plug. Will that be all plug & play??

We did the whole thing with axle stands. It was a pity fiddly getting the box fitting onto the spline but realised to get the teeth fitting it was easiest to have one person moving the shaft atthe back of the box at the same time as wiggling the box in. Sorry if that's a poor explanation.....

Got spigot bush?

I get what you mean about wiggling the box on and moving ths shaft at the same time to get it to line up etc?

Spigot bush...shit...

Where does the spigot bush go??

What about the FLYWHEEL, I don't see that on your list George.

what - turn the bushes upside down? hehe

That's the one Harry, but different to stagefumer, by turning the bushes 180 degrees in the shift lever, it actually shortens the throw inside the gearbox, whereas just shortening the length of the lever does nothing to the shift travel.

Does exactly the same thing in our R30's that $150 plus does to S13 & R31/32 etc.

Cheers, D

      Well, fun day was had, I finally found a house that will do me just fine, 1980's brick build, but with full fresh renovations, plus new colour bond fencing all round so puppies are incoming 🐕, and water tanks for the garden, and it's located in West Goulburn..... @Duncan 🫡, so day trips to Wakie to watch cars going Zoom will be on the cards In the end it cost well under my budget and was actually better than alot of the more expensive joints I was looking at, it is in a good area, close enough to the shops, public transport, and the Wollondilly River Weir,  and the great walking paths along the river, but far enough away from town to see minimal traffic The deposit is dropped, the conveyancer is conveyancing and I should get the keys in a week or 2 as the property is currently unoccupied  As with everything I own, I'm doing up a modifications list, as it doesn't have solar, that is first up on the big list, all of the panels and enough batteries to keep the joint warm, or cool, followed by a largish carport out the front, the small list, which will start as soon as I have keys, is some security stuff, like cameras, screens, and the usual "crazy prepper" additions that weird old people like (mouse holes to stick shot guns out of, and the usual man traps that the average person installs for the unsuspecting and unwanted guests 🤣) The gardens front and back are OK, but, not to my standards or liking, so landscaping will be a fun job to start getting into, so when spring is sprung I'll do a heap of planting, lots of natives and vegetables is the plan, the old owners were more "Old English Garden" type, so basically Roses and other weird looking things that are destined for the green waste bin One thing that is staying garden wise is a nice established hedge out the front, it is about 5 foot tall and covers the whole front of the property from prying eyes As for the car hoist, the roof in the garage has some height to it, but, I'll need to get an installer out to see what can be done, width wise may be a issue, but my building inspector will be getting back to me over the next week with his recommendations  Small, but cosy
